1) 5*(x-7)=3*(x-4)-27 2) 3x+2*(2x-3)=8-7*(x-2)

Question

1) 5*(x-7)=3*(x-4)-27 2) 3x+2*(2x-3)=8-7*(x-2)

Answer 1

1) 5*(x-7)=3*(x-4)-27

5х-35=3х-12-27

5х-3х=-39+35

2х=-4

х=-2

2) 3x+2*(2x-3)=8-7*(x-2)

3х+4х-6=8-7х+14

7х+7х=22+6

14х=28

х=2

Answer 2

5х-35=3х-12-27

5х-3х=-12-27+35

2х=-4

х=-2

 

3х+4х-6=8-7х+14

3х+7х+4х=8+6+14

14х=28

х=2
